Does anyone know an 아니메 girl that looks like this?

저기요 there! long time reader, firt time 질문 asker. I was wondering if anyone knows the name of a Blue-haired ghost girl character who's in an 아니메 with a long Japanese name. If it helps, she follows another girl around a lot, I think her name's Ichigo, but it'd be rilly helpful if someone could tell me the name of the anime.
